Participants

Reaction Steps

1 gm (3.3 millimols) of 5-hydroxy-1,2,4,5-tetrahydro-11methyl-3-azepino[4,5-b]quinoline-carboxylic acid ethyl ester was stirred for 2 hours with 20 ml of thionyl chloride at room temperature. The excess thionyl chloride was then distilled off in vacuo, the residue was dissolved in chloroform, the solution was dried with sodium sulfate, and the solvent was distilled off. After purification of the residue on a silicagel column with benzene/ethyl acetate (8:2) as the eluant, the yield was 0.55 gm (52% of theory), m.p. 131° C.
